. l TO ALL WIIOM I'l MAY C'ONCERN:

Be it known that. I, JOHN M. Merian, ot' Pittsburg, in the county ofAllegheny, and State of Pennsylvania, have invented a new and improved`Machine for ther Manufacture of Brick; and I do hereby declare thefollowing to be a full, clear, and exact description of 'theconstruction and operation of the same, reference being had to theannexed drawings, made a part of this specification, in which- Figure 1is a perspective view, Figure 2 a transverse section, and Figures 3, 4,and 5 sectional views, with letters of reference marked thereon. ,l lhenature of my invent-ion consists in the arrangement and construction ota`new and improved soft-mud, self-tempering, portable brick machine, ofwhich the following is Aa description of itsia-rrangement, construction,and operation. .7

I construct the mudtub or hopper A which receives the clay of wood, incircular form, `ofany given size, and secure it with bands, with raisedmetal bowl in the centre, letter K, fig. 3, and place it on thecast-iron bedplate B B, fig. 1, made secure in the raised groove C castupon the bed-plate, which, with the parallel beam D i D, secures it inplace. The beam I) D passes across the centre of the tub, and is held inplace by bolts or rods ou the outside ofthe tub, secured to thebed-plate, through the centre ofr which the shaft E passes, withshoulder resting and revolving on a step in the bed-plate, throughwl'iiclrthe" shaft passes-to receivepthe spur-whe`el beneath, secured.by a key. The sickle or shear-spuds F, fig/3, through which the shaft Epasses, are firmly secured to the sides of the hopper by means of bolts,and-'remain fixed, over and beneath which the knives attached to shaft Eset, or, regulated by washers,rcvolvefcutting, crushing, pulverizing,and mixing the clay, which is placed in the hopper together with astream-fof water, as shown in fig. l; Bymeanslof the sickle orshear-spade F the cut-ting and crushing is consta-'nt and gradual,giving` increased surface and requiringr less l power. The lower knifeor sweep II, fig./3,'attachcd to shaft E, is made in curvedorsicklc'fornuwith drag or trail filling the space between the sides'ot`thc hopper and the raised bowl in the centre, (the bowl filling thespace to prevent the` sweep from carrying around an undue quantity oftempered clay,) carrying around the mixed clay to 'opening I in thebottom of the tub or bed-plate, and forcing the clay through the openinginto plunger-box beneath, shown in fig. 2.' The spur-wheel beneath,:rlitached to shaft E, connects with spurwheel No. 2, fig. 2, joined onthe end of power-wheel shaft with double-crank moving pitmen, connectingwith cutter L and plunger M, made of cast steel, as shown in fig. 2,with openings in the centre, through which shaft E revolveswhich can ormay be driven by cams or ccccntrics attached to shaft E in plunger-box,instead 'of double crank and pitmcn. The cutter L Vpasses before plungerM, severing fthe clay between opening I and uplungerbo.\', coveringopening I, preventing the return ot' thc clay into hopper A when plungerM forces the clay from thc open end of plunger-box into the moulds inplace in large brick-wheel. llunger M is regulated by means of anadjustable bur on pitmen, so as to admit arequisite amount of clay Aintoplunger-box and no more, to be forced out, and upon withdrawal forminga. vacuum und causing a suction, thus aiding the knife or sweep H inrefilling the box, the knife L working backward and forward in advanceof plunger M. Theplarge metal brick-wheel N, fig. I,I construct of anygiven size, with shaft passing through `the centre, resting upon arms ofthe bed-plate, te which it is secured by boxing, and provided with theslots 0 0 at equal distances, with grooves on both sides of the buse toreceive and keep in place the brick-moulds, which arc provided withslides.I The wire P attached to the side of the wheel at the end of theslots O O prevents the moulds from passing beyond their` places, and isso arranged as to leave an opening for the removal of loose sand or dirtat the buse of the slot. The wheel N is provided with cogs upon the rim,by which, at regular intervals, it is drive'n by a one-fourth cog-wheclconnecting with power "beneatln The brick-moulds being placed in thcslots O O, are carried around, by thc revolution of wheel N, to the openend of plunger-bor, when and` where they are filled in turn bythe actionof plunger M, and when filled, while in pressure, before the withdrawalof the plunger, the knife Q, fig. 1, passes down betweenfthe mouth ofthebrick-mould andthe end .of plunger, cutting ofi' the clay smooth on thetop of the mould, and acting as a covering for the mould, keeping theclay` in place until the withdrawal of the plunger, when the knife Qrises and wheel N revolves, acting as an olf-bearer, carrying the mouldsthus filled up, Vevery second revolution of .the enefourth cog-wheel, toa level, when the mould is forced out from the slot on to .'t table, bymeans of the arm R- pnssng through the slet, which is u pci-rt of shaftS extending above and parallel with beam D D, upon which it rests byIneens of uprights; the shaft S connecting with shaft E by menus ofpinion-wheels R R,Whieh give' it power. On shaft S, place n. one-fourthcam, T, which :Lets in und upon the stop-cem frame U, which is attachedby :trod to knife Q, causing it to rise and fall when shaft S revolves,cutting away all excess of clay from the moulds, which is retained inplungerbox. I construct the mould W ofsteel, (see figs. 4 und 5,) withslides to enter the grooves in slots O O, of the size of two or morebricks, the bottom swinging upon hinge which forms one of the slides,the other bein-g riveted to the opposite side. When the mould is fulland upon the table, thefbrick is removed by inverting the mould andlifting the leaf or bottom, admitting the air, when the mould is readilyremoved from the brick, then sanded and replaced in the slot`0 of wheelN before it descends.

Whut I claim ns my invention, and desire to secure by Letters Potent,:1re-

The sickleror shenr-spuds F and lower knife or drag H in hopper A, incombination with the raised bowl,A constructed, arranged,Y and operatedin manner set forth. Y Y

I claim the knife L and plunger M, constructed and applied in manner undform substantially as described.

I claim the briel -wl1eel N, with slots and grooves to admit moulds,operated substantially as set forth.

claim the arrangement of the stop-cam U in connection with knife Q mdnrmRQ arranged und operating in manner described.

claim the mould with hinged buse, constructed und used as described toand for the purpose intended.

n testimony whereof I, the said JOHN M. MOYER, have hereunto set myhond.
